▎ 摘  要

NOVELTY - Anode slurry comprises a positive electrode active material, a conductive material, a binder and a solvent, where the ratio of the average particle diameter (D50) of the positive electrode active material to the average particle diameter (D50) of the positive electrode slurry is 1.5 or less, and the phase angle at 1 Hz of the slurry is 50 degrees or more. USE - The anode slurry is useful for forming anode used for lithium-sulfur batteries. ADVANTAGE - The slurry has excellent electrochemical properties, and excellent flowability while having high solid content, and improves the productivity and economic feasibility of the manufacturing process of the anode for lithium-sulfur battery. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) an anode for a lithium-sulfur battery, comprising a positive electrode active material layer formed using the anode slurry; and (2) a lithium-sulfur battery comprising anode, negative electrode and electrolyte.
